Fixture checks hardness at sprocket
roots
A dual purpose fixture enables Rockwell hardness tests to be made in the roots of sprocket and at specific points on the sprocket faces.
Indentec has developed a dual purpose fixture to enable Rockwell hardness tests to be made in the roots of sprocket and at specific points on the sprocket faces Used on a production basis by GKN Bound Brook, the fixture ensures repeatability in testing induction hardened surfaces on sintered metal sprockets on an Indentec digital Rockwell testing machine

Stainless steel robotically hardness tested
Believed to be the first that a digital Vickers hardness testing machine has been adapted for robotic operation, a system has been configured for a Spanish stainless steel plant.
For the test in the tooth root, the sprocket is mounted vertically on a hub and the root located by peg.
The fixture is locked and slid on guideways to a stop.
This positions the root exactly beneath the machine'' nose mounted indenter, which is chisel shaped to allow the test to be made in the base of the root.
For production needs, the sprocket is held by a quick release mechanism so that it can be rotated on the hub for tests on other teeth.
Tests on the sprocket face are preformed with the sprocket horizontal in a turret mounted on the same test table.
The tooth root is located by pins to ensure that tests can be made accurately at predetermined radial intervals from the tooth root.
The fixture is designed to accommodate different sizes of sprocket.
